CURTAIN-WINDOW INSTALLATION.

Application filed January 14, 1925. Serial No. 2,288.

This invention aims to provide an improved curtain window installation.

In the drawings, which illustrate a preferred embodiment of my inventionFigure 1 is an inside elevation of the in,- stallation, partly brokenaway to show under lying parts;

Fig. 2 is a fragmentary View of a corner of the installation showing oneof-the frame members partly broken away;

Fig. 3 is an enlarged section on theline 33 of Fig. 1;

Fig. 4 is an enlarged Section on the line 4.4 of Fig. 1;

Fig. 5 is an enlarged section on the line 55 of Fig. 1; and

Fig. 6 is an enlarged section on the line 6'-6 of Fig. 2. i

Referring to the draWings,'I have shown a curtain window installationparticularly, though not exclusively, useful in connection with vehiclecurtains. The installation, as illustrated, includes a curtain fabric1,.a light of glass 2 and a plurality of frame members for positioningthe glass relative to the curtain.

The purpose of this invention is to provide a simple, inexpensive anddurable installation which includes securing some of the frame membersto the curtain permanently so that it is not necessary to remove themwhen the glass is to be replaced. To this end,

I provide a one-piece frame member 3 pre senting a plurality of prongs 4and a Second frame member 5 presenting a plurality of prong-receivingslots 6 (Figs. 1 and 4) for cooperation with the prongs 4:- These framemembers 3 and 5 are secured to opposite sides of the curtain 1, asillustrated, by the prongs 4 substantially as shown and described in mycopending application Serial No.2,287. filed herewith. These frame parts3 and 5 are formed substantially as shown and'described in theabove-mentioned application. The frame member 5 presents an upstandingwall portion 7 at its inner periphery so that when the frame members 3and 5 are secured to the curtain 1, the glass may be inserted in thespace provided by the wall 7 and be supported at its periphery therebyto prevent lateral shifting of the glass. The frame member 3 projectsbeyond the wall 7 to support the glass at one face thereof (Figs. 3, 4and 5), the curtain 1 being interposed between i the glass 2 and theframe 3.

The glass 2 is cushioned at all contacting surfaces by a cushion strip 8of uncured rubber or the like, which is stretched about the periphery ofthe glass and overlies a portion vided with a plurality ofscrew-receiving holes 11. The third frame member 9 also presents anangleshaped'pOrtion at its inner periphery, which includes a flangeportion 12 (Fig. 5) extending over a portion of the glass 2 to supportthe remaining 'unsupportedface thereof. This frame member 9 may besecured to the rest of the installation by screws .13, of theself-tapping variety, which pass through the'holes 11, through holes 14in the frame 5, through the curtain 1 and thread themselves intodistorted neck portions 15 formed in the frame member 3,asbestillustrated in Fig. 5. Thus the third frame 9 may be easily andquickly removed from the rest of the installation by removing the screws13, so that the glass may be changed without disturbing the rest oftheframe members. The frame members 5 and 9 are each formed from severalpieces of metal presenting overlapping joints secured together by eyeletrivets 16, substantially as shown and described in the above-mentionedapplication. Thus the frames 5 and 9 may be made from the centers of theframe 3, thereby greatly reducing-the cost of manufacture and usingmaterial which would otherwise be Waste, in so far as curtain windowframes are concerned. Because of the overlapped joints and the rivets16, as shown'in Figs. 2, 3, 4; and 6, the frame 9 cannot lie against theframe 5,but touches only the rivets 16, thereby being spaced away fromthe frame 5 and also from the bent-over prongs 4, as shown in Fig.6.However, this space is useful inasmuch as it provides means wherebytension may beexerted upon theframe member 9 to hold the glass firmly inplace, when the screws are secured to the frame. The

screws 13 are placed at points between the joints of the frames (Fig,1,). so that, tension will be distributed evenly throughout the en. tireframe.

While I have shown and described a preferred-embodiment of my invention,it will be understood that changes involving-omission, substitution,alteration and reversal of parts may be made Without departing from thescope of my invention, which is best defined in the following claims,
